To all whom it may concern:

Be it known that I, Pn'rnaAvnlA SENE- CAL, of the city of Winnipeg,infthe Province of Manitoba, Canada, have invented certain new anduseful Im rovements in CarPipe Line Couplers, of w ich the following. isthe My invention relates to a coupler for efiectuall inter-connectingthe train line,- the signa line, and the steam heatin line in a train ofcars, and the objects of t e invention are firstly, to provide aninexpensive, serviceable, and efiic1ent device, which 'willautomatically couple and efiect a direct inter-connection between theseveral pipe lines of a train of cars; secondly, a device which willautomatically reset itself after having acted; and lastly a device whichwill release anddis-eonnect the pipe lines when adjoining cars part orbreak coupling.

It consists essentially in equipping each car of a train of cars with acomp emen'tary set of laterally and vertically movable j awadjoiningcars being designed to engage with each other; means forinter-connecting the pipe lines with the respective heads so that acontinuous line is effected when the heads are inter-connecteijand forautomatically locking the adjoining heads when they are broughttogether, and also for unlockin them when: the cars break coupling anmeans for resetting itself after the cars have g the parts bein arran edand constructed in etail as ereina ter more particularly described. 7

' Figure 1, represents aside elevation of a portion of. two adjoiningcars equipped with my invention. Fi 2, is a plan view as in 1:, the carsan couplers being shown in dotted outline. 3, is an enlar ed vertipipeline coupler, the headf being shown in si e elevation. Fig. 4, is avertical section noted by the line X X. in Fig. 3-. Fig. 5, is a furtherenlarged plan view of. two of the heads'inter-connected the one theother, parts being broken away to expose the con struction. 6 is alvertical cross sec-ftional view through one of. the heads, the sectoiibeing taken on the plane denoted by theline Y Y, Fig; 5.-

pivot pin 14'.

encircling the shaft.

1' and 2 represent a portion of the ends of two'adjoining cars of which3 are the supporting floor-beams.

4 and 5 represent the ordinary car couplers for interconnectin andthroughout specification. will be referred to as the car couplers. Thecar one car with the-other couplers form no part of my invention and maybe of any of the forms now in use.

. 6 and 7 are brackets securely fastened by bolts 8 to the under side ofthe cars at the ends, one directly in line with the other and spacedlongitudinally of v the car.

9 are cross dplates securely bolted to the brackets 7 an 8 and passlongitudinally of the cars. l

10 are cylinders laced directly beneath the plates 9 from w ich. theyare sus ended in each case by means of a central sa die 11 supported by.a swivel eye 12 which is received between two depending lugs 13 passingdownwardly from a plate 14. The latter plate is secured to the crossplate 9 and the eye is connected to the lugs by means of. a

it will allow the cylinder to turn in either a horizontal or verticalplane, the reason for which will shortly be apparent.

15 and 16 are coil springs passing between the extending ends ofthecylinders and the cy rs normally in a horizontal position and preventingany loose motion or play.

17 and 18 are two complementary jawshaped heads through the agency ofwhich the p'pe lines are inter-connected, as later explained.

19 are circular shafts lpassing backwardly from the heads, of whic theyform a part.

F The shafts pass into the cylinders 10- and it will be noticed thattheir cross sectional area is somewhat less than the internal crosssectional area of the cylinders. Consequently there is formed betweenthe shafts and the cylinders an anmilar chamber 20. The ends Thisarrangement is such that r cross (palates 9 in this way tending to keepthe of the cylinders are partially closed over at 21 and 22 to form asuitable bearing for the shafts, and the flanges so formed provide anabutment for a set of springs 23 and 24 which are placed within theannular chamber and The springs are separated by a collar 25 which issecured firmly on the shaft and free to move with the shaft, ga'ckwardlyand forwardly within the cham- The heads are formed by cutting avertically directed V-shaped channel in each of them in a manner toproduce a long and a short jaw 26 and 27 respectively. The head 17differs from that 18 only in so far as that it is the reverse orcomplementary, that is to say, when the two are placed together theshort jaws are on opposite sides and the long jaws adjoining. Each headis rovided with three ducts or osts 28, 29, an 30,

respectively, which lead rom the inner face 31 of the long jaw 26 to thebase 32 of the head. The ducts arearranged in each head so that when theheads are placed together they will be continuous or registering. The

train lines 33, the signal lines 34, and the steam lines 35 with whichthe ordinary cars are already equipped 'are collected and interconnectedthrough any suitable detachable joint with the ports 28, 29, and 30,respectively, "the connection being made at the base of the head, asshown.

36 are rubber gaskets placed or screwed into the ends of the ducts 33,34, and 35, where they open to the inner face of the jaws 26. Thegaskets prevent any leakage occuring in the transmission line betweenthe heads when the heads. are brought together. Each of the jaws 26 haveprovided in their outer face 37 a recess.or slot 38 the one wall ofwhich 38 is curved and the other 38 straight, the straight wall beingtoward the tip of the jaw. Each of the short jaws 27 of the heads isrecessed at 30, the recess being closed over by a plate 40 which is 35bolted to the head.

41 is a bell crank pivotally secured within the recess by a pin 42 andfree to operate therein.

43 is a locking pin or bar inter-connected.

4 with one of the arms of the bell crank by a pin 44. The end of the barpasses horizontally throu h an opening provided in the jaw and exten sbeyond the mner face 45 of the jaw, its position being designed so thatit 45 willenter the slot 38 formed in the outer face of the jaw 26.

,4 Zis.;;a spiral spring abutting 'one of the walls of the recess 39 atone end and the inner end of the locking bar 43 at the other.

The spring is employed to continuously press t e locking "bar to itsouter position so that it will normally be set for engagement with theslot.

. 47 are bars secured at their upper end firmly to the brackets 7 andhave their lower ends looped or turned back on themselves at 48 in orderthat each may receive and su port a longitudinally movable rod .49. T ebars 47 are positioned so that the rods may pass through an opening 50provided in each head, the opening entering directly to the recesses 39which admits of the bars being fastened to the free arms of the bellcranks. The extending ends of the rods are turned upwardly at 51 to forma stop. In practice it may be found advisable to place an adjustablestop on the rod which could be done by providing -a short sleeve carryina set screw. It is necessary, in order t at the rod may adjust itself tothe various positions that the head may assume, to have a universaljoint inserted in the rod at 52 between the brackets 7 and the ointwhere it enters the head. It isconsi ered that it is unnecessary tofurther refer to the universal joint as its use and construction is wellknown.

53 are guides secured to the heads, one at either side, and they areprovided in order to insure that there will be perfect contact betweenthe heads as that will always tend to direct the jaws so that the ductswill register. I have found it necessary to provide these guides for thereason that the floors of the cars are not always the same height abovethe tracks, .and that consequently if a high and a low car were to becoupled together the ports in the heads would not register, but would bedisplaced the one above the other. With these guides such a condition isimpossible.

In order to better understand my invention I will now describe its oeration assumin at the outset that t 0 cars are coupled and the pipeline cou ler is connected as shown 1n Figs. 2 an 5. If for any reason,either redetermined or acci dental, the car coup ers 4 and 5 are undoneor break coupling, the heads 17 and 18 will remain inter-connected untilsuch time as they are extended till the sto s 51 on the rods 49 engagethe loop of t e bars 47. The springs 23 and 24 allow the shafts 19 toextend and consequently the heads to remain coupled. As soon as thestops reach the 100 48 and the cars continnue to part the loc g bars arewithdrawn from. the slots 38 by means of the action of the rods and thebell crank. This allows the heads to part coupling and consequentlydisconnects the ducts or ports 28, 29 and 30, and consequently the hnes33, 34, and 35. As soon as the heads part coupling the s rings 23 forcethe shafts and consequent y the heads from their extended position, tothe normal osition, and this motion frees the stop 51 reset thelocldngbars 43, that is, force them to their outer position. When twocars are being coupled the heads receive each other and the locking barsare primarily forced om the loop 48 and the springs 46 inwardly withinthe short jaws 26. However as soon as the slots 38 are opposite thelocking bars the bars spring outwardly due to the sprin s 46 and 100 theheads together.

What I c aim as my invention is:

1. In a device of the class described, the combination with the car of acylinder ivotally supported beneath'the car and aterally swingable; ajaw-shaped head having a rearwardly extending shaft passing into thecylinder a collar on the shaft; and a spring interposed between thecollar and the respective ends of the cylinder, as and for the purposespecified.
